A chain of turnpikes connecting Baltimore, Maryland, to the National Road at Cumberland was completed in 1824, forming what is referred to as an eastern extension of the National Road. In 1835 the road east of Wheeling was turned over to the states for peration as a turnpike. It came to be known as the National Pike, a name also applied to the Baltimore extension. The modern U.S. Route 40 between Baltimore and Cumberland continues to use the name Baltimore National Pike today, and a spur into the Washington, D.C. area (part of Interstate 270) is known as the Washington National Pike.
